Howdy! I had this issue on 4.x, which is basically, I have machines that do cgi stuff for customers, and there is a local md device that is used as a tmp. When it fills the machine logs errors vnode_pager_putpages I/O error 28.. and the machine is unresponsive and needs to be power cycled. There is a previous thread on this issue http://atm.tut.fi/list-archive/freebsd-stable/msg19031.html and a subsequent patch for 4.x http://atm.tut.fi/list-archive/freebsd-stable/msg19288.html that I appled to 4.x and it solved the problem. Now that I have upgraded to 6.2, the problem has recurred, but the previous patch is no longer valid. Is there something wrong with the patch/solution given, and is there a solution for 6.2? thanx - steve

Constructing a similar patch for 6.2 should be trivial. -Kip

Is this issue resolved completely with this patch? [1] http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/67919 Thanks -cs

Is this issue resolved completely with this patch?Not sure yet. I'm running some machines with the patch and some without, hoping that the unpatched machines will fail and the patched ones won't. Havn't been able to reproduce the problem to conclude. But I'll let you know ... -steve> > [1] http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/67919 > > Thanks > -cs >
